Verall Functional Features:

1- Hydraulic System:
① Utilizes a dual-pump system and the Rui Si Kai hydraulic control system. Each machine is meticulously factory-tuned by the Super Field Frog, ensuring delicate, linear, and smooth movements.
② Uses independently developed gear pumps: High-precision processing, high efficiency, low noise. The pressure remains stable at 6-8 MPa at medium to high motor speeds and 4-6 MPa at low speeds.
③ Adopts independently developed directional control valves: Extremely precise processing, excellent sealing performance, outstanding linearity, and micro-control capabilities.
④ The oil tank, gear pump, and directional control valve are connected with oil blocks, ensuring a compact and reliable structure to prevent oil leakage.
⑤ Hydraulic system features copper tube welding and high-pressure resistant hoses, providing stability and reliability. Standardized interfaces allow for quick upgrades in the future.

2- Modular High-Fidelity Design of the Entire Machine:
Impeccably replicates real machine details, with an exquisite appearance. The excavator arm is made of stainless steel 304, and structural components are CNC machined.

3- Hydraulic Wrist:
Key components such as the rotating gearbox, hydraulic clamp, hydraulic quick change, oil-electric slip ring, etc., undergo precision CNC processing. The structure is reliable, durable, and aesthetically pleasing. The quick change has standardized interfaces, making it compatible with various attachments, adding more fun to machine operation.
